Examples of org.locationtech.udig.catalog.IGeoResourceInfo

org.locationtech.udig.catalog.IGeoResourceInfo
Represents a bean style metadata ancestor for metadata about a geoResource.
The methods within this class must be non-blocking. This class, and sub-classes represent cached versions of the metadata about a particular service.

Much of this interface is based on Dublin Core and the RDF application profile.

Any changes to this content will be communicate by an event by the assocaited GeoResource.
